Unfinished 2x10 vent covers were not available when we purchased flooring. Salesman gave us a finished 2x10 vent cover for carpenter-installer to use as a placeholder. Only after we returned the finished vent cover to pick this UNfinished vent cover did we find out that the UNfinished vent cover was slightly smaller than the finished version. Floor was already installed at that point and the carpenter had to "improvise" to get this vent cover installed in a space that was too large for it.
